Question

solid Packing of particles​

Answer 1

$\huge{\underline{\mathfrak{Answer:-}}}$

Near crystal packing refers to the effective arrangement of constituent particles in a crystal lattice in vacuum. We have to assume that all particles (atoms, molecules and ions) are of the same spherical solid form to grasp this set more precisely.

Answer 2

Answer:

Close packing in crystals refers to space efficient arrangement of constituent particles in a crystal lattice. To understand this packing more clearly we have to assume all particles (atoms, molecules and ions) are of the same spherical solid shape. So the unit cell of a lattice is a cubic shape.
